Figure 6. Serial-Interface Communication Cycle
Figure 7. Serial-Interface Timing Diagram
A serial interface programs the MAX19515 control reg-
isters through the CS, SDIN, and SCLK inputs. Serial
data is shifted into SDIN on the rising edge of SCLK
when CS is low. The MAX19515 ignores the data pre-
sented at SDIN and SCLK when CS is high. C C S S must
transition high after each read/write operation. SDIN
also serves as the serial-data output for reading control
registers. The serial interface supports two-byte transfer
in a communication cycle. The first byte is a control
byte, containing the address and read/write instruction,
written to the MAX19515. The second byte is a data
byte and can be written to or read from the MAX19515.

cation cycle as either a write or read transaction (0 for
write operation and 1 for read operation). The following
7 bits specify the address of the register to be written or
read. The final 8 SDIN bits are the register data. All
address and data bits are clocked in or out MSB first.
During a read operation, the MAX19515 serial port dri-
ves read data (D7) into SDIN after the falling edge of
SCLK following the 8th rising edge of SCLK. Since the
minimum hold time on SDIN input is zero, the master
can stop driving SDIN any time after the 8th rising edge
of SCLK. Subsequent data bits are driven into SDIN on
the falling edge of SCLK. Output data in a read opera-
tion is latched on the rising edge of SCLK. Figure 7
shows the detailed serial-interface timing diagram.
